Tree Nutri Product Application
For Distressed Trees with Obstructions
1. For trees that have obstructions blocking access to a tree’s entire drip line, such as trees that are between
sidewalks (as shown in Fig. 2),create as close to a circle as possible around the tree to resemble the drip line.
a. For this example, assume that only half of the drip line circle is accessible. Create additional semi-circles both
inside and outside of the drip line. Drill holes on these semi-circles and apply the same amount of Tree Nutri,
in total, as would have been applied if there weren’t obstructions.
2. After the drip line semi-circle has been identified, use the Tree Nutri™ Hydrojet to “drill” one hole every 1.5-2.0
feet on the circumference of the semi-circle.
a. Each hole should be 8-10 inches deep, with the diameter being roughly 1 inch.
3. Once the holes have been drilled, apply 2 ounces of Tree Nutri to each hole via the Tree Nutri™ Funnel.
4. After filling all holes in the drip line semi-circle, proceed to follow steps 2 through 3 for a semi-circle 1.5 feet
inside the drip line semi-circle.
5. Repeat steps 2 through 3 for as many additional semi-circles, each 1.5 feet outside of the preceding semi-circle,
as required to be able to drill the same number of holes for the tree as would have been required, without
obstructions.
a. Each hole should optimally be offset by about 1.5 feet from the holes in the adjacent semi-circle.
The following table shows the number of holes that would need to be drilled for a tree with a drip line 10 feet from the
trunk, with obstructions (as illustrated in Fig. 2):

For Trees in Severe Distress with Obstructions
If the tree is in severe distress, it is recommended to drill additional semi-circles within the inner most circle, following
steps 2 through 3 as above, to drill the same number of holes as would have been required without an obstruction.
Most active tree roots are found within 1.5 feet inward and outward of the drip line. To maximize effectiveness, Tree
Nutri needs to be applied near as many active root tips as possible in this range to stimulate accelerated mitosis. The
additional treatment holes are usually deemed necessary when trees are in severe distress as it is likely the tree’s root
tips have receded well inside the drip line.
